MVC renders Double as empty string

Question

Within a view I have the following code:

@foreach (var ce in Model.MyObjectCollection)
{
    <p>
        Target: @ce.Target.ToString("#.##")%
        <br/>
        Level: @ce.Level.ToString("#.##")%
    </p>
}

If either the value of Target or Level is 0.00, then MVC simply renders that out as an empty string. Debugging shows the value of each to be 0.00.

I need zero values to render as 0.00%.

Can anyone advise if I'm doing something wrong?

The # format specifier won't display zeros

Note that this specifier never displays a zero that is not a significant digit, even if zero is the only digit in the string. It will display zero only if it is a significant digit in the number that is being displayed.

You can use the 0 specifier instead

ToString("0.00")%

Use zeros instead of #:

@ce.Target.ToString("0.00")%
